    Penske doesn't have the software needed to accurately troubleshoot engine problems. Not a huge deal on trucks up to 07, but after that its impossible. Sent from my DROIDX using EO Forums mobile app

    This is a fair assessment. From what I'm aware of, most Hino dealers are also dealers of more popular brands, and much more focus is put on training mechanics for popular brands of trucks. Some places have trained people, but rarely see a Hino, so whatever they've learned in training quickly...

    Most of my thoughts on that disaster is that your dealer was incompetent. They have direct access to a technical service representative that has access to a huge amount of troubleshooting information, and that has power to authorize repairs outside of warranty. I work at a Hino-only...

    They have nitrided cylinder liners, which are rock hard. They don't wear much unless severely overheated. Mechanics that are used to savagely overtightening everything will not be a fan of Hinos, and vice versa. Sent from my DROIDX using EO Forums mobile app

    Good call. I forgot that button existed, because I never use it. If one comes in with an ABS fault, I hook a laptop up to it using a NEXIQ interface then I can talk to it using Meritor Wabco Toolbox software. Later models, 11-up do away with the diagnostic button. You'd have to attach to...

    NAG1 Fluid

    This is one of many reasons why a lot of new cars don't have dipsticks for the transmission. People are going to buy the cheapest red fluid they can find, and when they pour it in it'll be way overfull. Then it'll blow up, and he'll tell all his friends that 'Brand X is junk!' I still see...

    Lucas oil stabilizer and below zero temps

    I have one of these on the oil pan of my Kubota tractor. It definitely helps cold starts. A big engine might need a couple. They can also be glued to metal radiator tanks. Smaller ones can be stuck to batteries, but they don't really regulate temperature, so not a good idea to leave plugged...

    Lucas oil stabilizer and below zero temps

    Are the batteries also at ambient temp? They will be effectively reduced to around 50% capacity if they're at -15F. I'd point a kerosene heater or car exhaust toward the battery box for about 15 minutes, and see if that gets her to whirl over any quicker.

    Not legally. Yeah, it'll run, it'll also have a permanent check engine light. Depending on software level, it may also derate. Is there a particular reason you want to, besides convenience? Sent from my DROIDX using EO Forums mobile app

    The blower motor looks like it'll lift straight out of the box, but it's hindered by the bar, and other stuff. After the four bolts come out of the firewall, the section of the box that the blower comes in is able to be moved, and then it's easy.

    What I'd look for if I was shopping for a Hino Let me start by saying that I'm not a truck driver nor do I want to be, and I know little about spec-ing a truck. All I do is fix 'em, and make maintenance recommendations. Of course, get service records. If they're unavailable, not all hope is...

    Mmmm...IHoP. The converter unlocks because if you suddenly had to stand on the brakes, the brakes would have to overcome both the inertia of the vehicle and the rotational inertia of the powertrain. In theory the engine could stall or the brakes overcome. Putting the transmission in a state...

    Trucks with Allison transmissions: if the ABS light comes on for any reason, its immediately time to stop and do some checks. You can't just keep driving without consequences. Pull off, set the brakes, chock it (don't get squished, in other words), and push all the speed sensors in. Twist and...

    Most of the subjects I've talked about so far have addressed problems caused by lack of maintenance, improper maintenance or repair, or improper operation. When they're maintained and operated properly, we don't see them roll up into the shop very often, aside from PM services. Does anyone...

    08-14 trucks have an exhaust brake. There's two adjustment bolts on it that limit total travel. If you're looking at it, thinking "hmm, that would work better if I adjust it so it turns farther", well, you're correct. They work GREAT if you allow them to shut further. However, if you do...

    Belts and hoses: aside from some of the 338's and the four cylinder engines, there's only a couple different serpentine belts. Before you take a belt off, take a pic or draw a picture of their routing. Its entirely possible to make either belt fit, but only one is correct. What happens is...

    If you've got the valve cover off for whatever reason, and you decide to start the engine, stay away from the injector wiring. There is a couple hundred volts there at an amperage significant enough to cause severe injury. If the shock don't kill ya, the involuntary spasm you'll have...

    Valve lash: interval is every 50k miles. They get loose over time. Too loose affects boost some, which can also affect soot buildup and Dpf regeneration. Really obnoxiously loose, the crosshead jumps up off the valves, lands on the valvespring retainers, and when the rocker presses down again...

    That bar that's in the way...we've seen a couple that were cut out then welded back in, or left out entirely, courtesy of people that couldn't comprehend that bolts sometimes go through firewalls.
